How To Clean Pool Water, Complete Guide and Product Reviews

How to clean pool water

It can happen to the best pool owners; you skip a couple of steps of pool water care, perhaps even a couple of weeks, the pool’s chemistry is off and there you have it: a green pool. It should be noted that this can happen to any type of pool, and inground as well as above ground pool water maintenance can be rather simple. This article will provide a step-by-step guide for the most efficient way to make your pool water crystal clear again. If you follow these, keeping your pool water clean should be the easiest thing!

  1. Remove Debris with a Leaf Net

    The very first step to cleaning an extremely dirty pool is removing the large pieces of debris from the pool. Using a leaf net, remove all the leaves, branches and bugs from the pool water and pool floor. The most important thing is not activating any cleaner, robotic, vacuum or manual, to remove the larger debris. Otherwise, you might ruin your swimming pool cleaner.

  2. Adjust the Chemical

    Now that your pool is clean of large debris, it’s time to adjust the chemicals, which are the most important part in any swimming pool maintenance. The chemicals that need to be balanced in their appropriate ranges are: the pH and Alkalinity.

  3. Shock the Pool

    A very dirty pool needs to be “shocked” in order to be thoroughly cleaned, that is, the bacteria and algae need to be disinfected as aggressively as possible. This is achieved through chlorinating the water with as much liquid chlorine as possible. There is no maximum amount of chlorine, and the more you use, the faster the pool will be cleansed. Continue until the water changes color.

  4. Run the Filter for 24 Hours a Day

    Once the pool is disinfected and cleared of bacteria, you can start filtering the water. After all, it’s filled with chlorine and small debris leftover. Turn on your filter 24 hours a day, and backwash a couple of times throughout the day. Remember, you cannot overclean your pool – backwash and clear your filter as many times as possible for an effective cleaning process.

  5. Clean the Pool Floor

    After a couple of days and once your water turns crystal clear, you might see some leftover debris covering your pool surface. This would be an ideal time to activate your robotic pool cleaner, for a meticulous cleansing of your pool surface, walls and pipeline. Now that the larger chunks of debris are gone, and the pool chemicals are balanced, your cleaner can make sure that the level of cleanliness is well-maintained.
